Abstract (en)

[origin: WO2010141713A2] There is provided a process of forming a regular array of rows of subpixels on a workpiece. The subpixels having four different colors, and a subpixel pitch s. Of the four colors, q colors are formed by printing and r colors are formed by a non-printing method. The process includes the steps: (1) providing a printing head having z nozzles arranged in a row with a spacing between the nozzles of p, where z = 4n1 and p = 3s, the printhead being at a first position relative to the workpiece; (2) providing q different printing inks, one for each of the q printed colors; (3) supplying each of the printing inks to the nozzles in a regular alternating pattern; (4) printing a first set of z rows of subpixels with the printing head; (5) moving and printing in a first printing pattern by: (a) moving the workpiece laterally relative to the printing head by a distance d1, where d1 = 4n2s; (b) printing a set of z rows of subpixels with the printing head; (6) moving and printing in a second printing pattern by: (c) moving the workpiece laterally relative to the printing head by a distance d2, where d2 = d1; (d) printing a set of z rows of subpixels with the printing head; (7) moving and printing in a third printing pattern by: (e) moving the workpiece laterally relative to the printing head by a distance d3, where d3 = 4n3s, such that d1 + d2 + d3 = pz; and (f) printing a set of z rows of subpixels with the printing head; (8) repeating steps (5) through (7) multiple times in the same order; and (9) applying r colors by a non-printing method; where: n1 is an integer greater than 0; n2 is an integer greater than 0, such that the integer is not a multiple of three and n2 = n1; n3 is an integer such that 2n2 + n3 = 3n1; q is an integer from 1-4; and r is an integer, such that q + r = 4.
